| Summary:
We propose an architecture for scheduling network operations enabling the
end-to-end generation of entanglement according to user demand. The main
challenge solved by this architecture is to allow for the integration of a
network schedule with the execution of quantum programs running on processing
end nodes in order to realise quantum network applications. A key element of
this architecture is the definition of an entanglement packet to meet
application requirements on near-term quantum networks where the lifetimes of
the qubits stored at the end nodes are limited. Our architecture is fully
modular and hardware agnostic, and defines a framework for further research on
specific components that can now be developed independently of each other. In
order to evaluate our architecture, we realise a proof of concept
implementation on a simulated 6-node network in a star topology. We show our
architecture facilitates the execution of quantum network applications, and
that robust admission control is required to maintain quality of service.
Finally, we comment on potential bottlenecks in our architecture and provide
suggestions for future improvements.
